I am interested in how plants interact with each other and other organisms in their environment, as well as the influence that human activities such as agriculture have on these interactions. My research aims to develop a better understanding of how field margin management, with an emphasis on perennial biodiversity plantings, affects associated weed and insect communities. On-farm biodiversity is a vital component of sustainable agriculture, and the establishment of native species near crop fields benefits farmers by attracting pollinators and insects that act as biocontrol agents. However, it is unclear how these plantings affect existing weed communities, or if the species commonly used in these plantings have the potential to become weedy themselves. The long-term goal of this research is to identify best management practices that allow farmers to maximize ecosystem services while simultaneously limiting competition between crops and weeds.
